Mosese Kurulala and Iliakini Raderua pleaded guilty to violations, which are not crimes under US law.

The four were sentenced to community service and fines.

Shute, who is the only British member of the squad, was given a one-year conditional discharge, ordered to carry out five days of community service and fined $500 (£314) at the New York criminal court.

He was also told to pay fees and a surcharge totalling $250 (£157).

The other three, who are all from Fiji, were sentenced to community service and fines.

All four men serve in the Royal Scots Borderers, an infantry battalion of the Royal Regiment of Scotland.

Two other soldiers from the same battalion were also arrested in connection with the brawl but their charges were dropped.

A battalion spokeswoman said: "We have noted the findings of the court.

"Those who have been charged in relation to criminal offences will have that recorded on their record and it will affect their careers.

"Those who have had their charges dropped may still be liable to administrative action at the discretion of their commanding officer."

The Ministry of Defence warned that those who fell short of army standards faced disciplinary action and could be discharged.

A spokesman said: "All those who are found to fall short of the army's high standards or who are found to have committed an offence under the Armed Forces Act are dealt with administratively – up to and including discharge – or through the discipline process, as appropriate.

"We have a common law and Data Protection Act duty to protect the personal information of our employees and, as such, we are not prepared to release any personal information relating to this case."
